In need of a new heat source in a house I’ve just bought. Have been considering a viessman 200 boiler but am tempted by a heat pump from octopus. It’ll be £4-5k after the grant. Since they offer finance this would be very cheap if dragged out over 10 years, so I’m considering spending the cash on a battery to make use of cheap overnight power to run the HP.

Any downsides to this plan?
